Daylight Portals in Revit 2017?

[robinhillrhca700396]

Been told to use Daylight Portals option in an internal render in Revit 17.
Did this option disappear after Revit 16 or has it moved elsewhere? If so where?
Are they automatically turned on in Revit 17, or have we just lost this quality improvement option?
Hope some one knows and can tell me.

Thanks
Robin
